Still More Counting

New Collections to Count

With the sharing problems introduced so far children will have seen pictures like this one.

                                             

  

  

They will have learned to call this a picture of "three fourths." 

But they may not have seen pictures like this one

                                                                     

  

and so they may not know how much this picture represents.

Similarly, children will have seen pictures like this

                                        

      

      

and should know to count "one and two fifths."

But they may not have seen pictures like this

                                                         

  

 

 

or know how to count what they see.

You can further extend your child's ability to count by using some simple subtraction problems.

Subtraction

¹

Here are three subtraction problems that can be used to lead your child to drawing pictures that they haven't seen before and "counting" to name the fraction that each picture represents. You should be able to make up a lot more just like them.

• Suppose that you had 1 banana and a monkey came along and ate one sixth of it.  How much would you have left?
  
• Suppose that you had 3 bananas and a monkey came along and ate one third of one of those bananas.  How many bananas would you have left?
  
• Suppoe that you had 5 bananas and a monkey came along and ate one and four sevenths of those bananas. How many bananas would you have left?
  

In this video, someone ate one third of Trixie's chocolate bar, and here someone ate one fifth of Rose's giant donut.
